Nice site….much more info than pool store.
Opened pool 4 wks ago for season. Greenish at first but cleared up in a couple of days. Added salt, vacuumed, backwashed filter. In process of shocking (day 4) now per pool store clerk. There are random, shadowy streaks on bottom and up sides – notice it more when cloudy; harder to see when sunny. A bit of white cloud when brushing. 2nd season - PB finished/opened pool last spring. What to do now? (Mustard algae, too much chlorine, keep brushing daily??) Thank you for any help!
Test results this am / last pm: rec’d TF100 yesterday
salt ok per SWG
